Re:  The Advisors' Inner Circle Fund III 485(a) Filing (File Nos. 333-192858 and
     811-22920)
     ---------------------------------------------------------------------------

Dear Ms. Dobelbower:

On behalf of our client, The Advisors' Inner Circle Fund III (the "Trust"), this
letter responds to the comments you provided on behalf of the staff (the
"Staff") of the U.S. Securities and Exchange Commission (the "SEC") via
telephone regarding post-effective amendment no. 86 under the Securities Act of
1933, as amended (the "1933 Act"), and amendment no. 90 under the Investment
Company Act of 1940, as amended (the "1940 Act"), to the Trust's registration
statement on Form N-1A, filed with the SEC pursuant to Rule 485(a) under the
1933 Act (the "Amendment") with respect to the MFG Low Carbon Global Fund and
the MFG Infrastructure Fund (each, a "Fund," and, together, the "Funds"). Below,
we have summarized your comments and questions, followed by our responses.
Capitalized terms not defined herein should be given the meaning provided in the
Amendment.

PROSPECTUS

COMMENTS APPLICABLE TO EACH FUND

1.   COMMENT. Each Fund's investment objective uses the phrase "medium to long
     term." Please define such phrase in each Fund's "Principal Investment
     Strategies" section.

     RESPONSE. The Trust has added the requested disclosure under the heading
     "More Information about the Funds' Investment Objectives and Strategies,"
     which is included in the prospectus pursuant to Item 9 of Form N-1A.

2.   COMMENT. In accordance with Instruction 4(f) to Item 3 of Form N-1A,
     please include a second Example and related narrative explanation showing
     the effect of each Fund's redemption fee under the "Example" heading in the
     "Fund Fees and Expenses" section.


                               MORGAN, LEWIS & BOCKIUS LLP

                               1701 Market Street
                               Philadelphia, PA 19103-2921     T +1.215.963.5000
                               United States                   F +1.215.963.5001

     RESPONSE. Instruction 4(f) to Item 3 of Form N-1A requires that a Fund
     include an Example showing "the second 1-, 3-, 5-, and 10-year periods and
     related narrative explanation only if a sales charge (load) or other fee is
     charged upon redemption." However, in calculating the Example pursuant to
     Item 3, each Fund must assume that an investor "invests $10,000 in the Fund
     for the time periods indicated." Since the redemption fee is imposed only
     on shares redeemed that have been held for 30 days or less, no redemption
     fee will be charged if an investor holds his or her investments for the
     time periods required by Item 3. Therefore, the Registrant respectfully
     declines to make the requested change.

3.   COMMENT. In the "Liquidity Risk" paragraph in each Fund's "Principal
     Risks" section, please revise the phrase "The Fund may have to lower the
     price" to clarify that the Fund may have to sell an instrument at a price
     lower than the price at which the Fund purchased it.

     RESPONSE. The phrase noted in this Comment has been revised to state "The
     Fund may have to sell its investment at an unfavorable price or time...."

COMMENTS APPLICABLE TO THE MFG LOW CARBON GLOBAL FUND SUMMARY SECTION

4.   COMMENT. The first paragraph of the "Principal Investment Strategies"
     section states that "Under normal circumstances, the Fund...invests at
     least 40% (or, if conditions are not favorable, at least 30%) of its assets
     in non-U.S. companies" (the "40%/30% Policy"). Please supplementally
     disclose how the Fund values derivatives for purposes of its 40%/30%
     Policy.

     RESPONSE. The Fund intends to take into account exposures created by
     derivative instruments for purposes of its 40%/30% Policy in a manner
     consistent with Rule 35d-1. For example, if a derivative creates an
     investment exposure to an issuer in an amount equal to the mark-to-market
     value of the derivative, the Fund would typically expect to use that value
     for purposes of its 40%/30% Policy. On the other hand, if a derivative
     creates an investment exposure equivalent to a cash investment in the
     underlying issuer equal to the derivative's notional amount, the Fund
     reserves the right to use that amount for purposes of its 40%/30% Policy.

5.   COMMENT. The first paragraph of the "Principal Investment Strategies"
     section states that "The Fund also may, but does not currently intend to,
     purchase or sell futures contracts and engage in short sales on exchange
     traded funds to reduce risks associated with the Fund's investments."
     Please consider deleting this sentence and disclosing these investment
     strategies only in response to Item 9 of Form N-1A.

     RESPONSE. The Trust believes that the disclosure noted in the comment is
     appropriately located in the Fund's summary section and, accordingly,
     respectfully declines to make the requested change.

6.   COMMENT. In the paragraph under the heading "Industry and company
     research" in the "Principal Investment Strategies" section, please clarify
     which measure(s) the Adviser's investment committee uses to determine a
     quality rating for a company.

     RESPONSE. The requested change has been made.

7.   COMMENT. The paragraph under the heading "Portfolio construction" in the
     "Principal Investment Strategies" section states that "The Adviser designs
     the Fund's portfolio to have lower historical volatility than that
     exhibited by world equity markets." If there is a more specific benchmark
     against which the Adviser manages the volatility of the Fund's portfolio,
     consider disclosing such benchmark.

     RESPONSE. The requested change has been made.

8.   COMMENT. In the paragraph under the heading "Low carbon framework" in the
     "Principal Investment Strategies" section, please explain in plainer
     English how the Adviser evaluates a particular company as part of its low
     carbon emissions overlay.

     RESPONSE. The requested change has been made.

9.   COMMENT. Since the "Principal Risks" section discloses general "Geographic
     Focus Risk," please provide applicable country- or region-specific risk
     disclosure if the Fund has a principal investment strategy to focus its
     investments in a particular country or geographic region. If the Fund does
     not have such a principal investment strategy, please confirm this
     supplementally.

     RESPONSE. The Fund does not have a principal investment strategy to invest
     in any particular country or geographic region and, accordingly, no
     disclosure has been added in response to this comment.

COMMENTS APPLICABLE TO THE MFG INFRASTRUCTURE FUND SUMMARY SECTION

10.  COMMENT. The first paragraph of the "Principal Investment Strategies"
     section states that the Fund invests in "companies in the infrastructure
     industry and related industries." Please consider removing mention of
     "related industries" or else defining "related industries" and explaining
     how they are related to the infrastructure industry.

     RESPONSE. The phrase "and related industries" has been deleted in response
     to this Comment.

11.  COMMENT. In the first paragraph of the "Principal Investment Strategies"
     section, please clarify what "social infrastructure" means.

     RESPONSE. The requested change has been made.

12.  COMMENT. In the "Principal Investment Strategies" section, please revise
     the paragraph under the heading "Determining the investment universe" to
     provide a plainer English explanation of the criteria that the Adviser uses
     to determine the Fund's investment universe.

     RESPONSE. The Trust believes that the second sentence of the referenced
     paragraph provides adequate detail on the infrastructure classification
     criteria used by the Adviser to determine the Fund's investment universe.
     Nevertheless, the Trust has revised the second sentence to clarify the
     "gearing levels" and "reporting transparency" criteria and note that the
     Adviser applies all criteria listed in the sentence to infrastructure
     investments.

COMMENTS APPLICABLE TO THE RELATED PERFORMANCE DATA OF THE ADVISER SECTION

13.  COMMENT. Please consider changing the title of this section to "Related
     Prior Performance Data of the Adviser."

     RESPONSE. The Trust respectfully declines to make the requested change
     because it does not believe adding "prior" where requested clarifies the
     disclosure. Adding the word "prior" could confuse investors by causing them
     to believe that the Adviser's performance is stale when instead it is shown
     as of the same date as the Fund's performance will be shown (i.e. , as of
     the most recent calendar year end preceding the effective date of the
     prospectus) once the Fund achieves a full calendar year of performance.

14.  COMMENT. (a) If accurate, please insert the word "all" immediately before
     the phrase "actual separate accounts" in the first sentence of the first
     paragraph of this section. (b) Please confirm supplementally whether any
     separate accounts managed by the Adviser that have investment objectives,
     policies and strategies substantially similar to those of the Fund were
     excluded from the Composite and, if so, why.

     RESPONSE. (a) The requested change has been made. (b) The Adviser confirms
     that no separate accounts managed by the Adviser that have investment
     objectives, policies and strategies substantially similar to those of the
     Fund were excluded from the Composite.

15.  COMMENT. In the fourth paragraph, please clarify how the second sentence
     relates to the first sentence or else delete the second sentence.

     RESPONSE. The second sentence has been deleted in response to this Comment.

16.  COMMENT. In the "Calendar Year Total Pre-Tax Returns" table, please
     consider (a) removing the "Dispersion" column and (b) giving exact numbers
     in the "Number of Accounts" column.

     RESPONSE. References to the "Number of Accounts" and "Dispersion" columns
     have been deleted.

17.  COMMENT. In the "Calendar Year Total Pre-Tax Returns" table, please
     consider removing the row for 2013 given that the Composite did not start
     until May 2013.

     RESPONSE. The Trust respectfully declines to make the requested change
     because it believes that the disclosure is relevant to investors and that
     footnote 4 to the table clearly discloses that such data is not annualized
     and is reported for the period from May 2, 2013 through December 31, 2013.

18.  COMMENT. Please confirm supplementally that the Adviser has the records
     that form the basis for or demonstrate the calculation of the performance
     of the accounts included in the Composite, in accordance with Rule
     204-2(a)(16) under the Investment Advisers Act of 1940, as amended (the
     "Advisers Act").

     RESPONSE. While the Adviser does not necessarily concur that including the
     Composite performance in the prospectus is an advertisement that is subject
     to Rule 204-2(a)(16) under the Advisers Act, the Adviser confirms that it
     will maintain records necessary to substantiate the performance.

19.  COMMENT. Please consider comparing the Composite's performance to the
     current index, the S&P Global Infrastructure Net Total Return Index, for
     all periods presented, given that the Composite's prior benchmark (the
     "Prior Benchmark") was discontinued.

     RESPONSE. The Trust respectfully declines to make the requested change. The
     Adviser has represented to the Trust that the Composite's performance is
     compared to the Prior Benchmark during all periods when the Prior Benchmark
     was operational and was the Composite's benchmark in order to comply with
     applicable requirements of GIPS(R).
